sight, smell, taste, touch, hearing

2

Name some senses

**he said he will not test us on this, but this is just thought provoking**

~Touch
~Sight
~Smell
~Taste
~Hearing
~Proprioception/ kinesthi
~Pain (visceral)
~Hunger/ satiety (visceral)
~Bowel/Bladder
~Temperature
~Tired/ malaise
~Vibration
~Thirst
~Need to breath
~Nausea
~Barognosis

3

what are the 2 main tracts that carry touch back?

~Dorsal column
~Anterolateral of spinothalamic tract

4

dorsal column- can also be called

medial lemniscus

5

sensory info traveling in dorsal column

~Proprioception
~Vibration
~light touch
~discriminatory touch

6

spinothalamic tract

anterolateral

7

sensory info traveling in Anterolateral of spinothalmic tract

~crude touch
~temperature
~pain

8

temperature can be easily tested by

asking the pts if your hand are cold/hot

9

Proprioception can be easily tested by

~move one arm to a position with eyes closed
~have him move the other arm to the same position (the joint know the position)

10

Vibration can be easily tested by

test with toning forks

11

Light touch can be easily tested by

~cotton (up and down so that hair does not get involved)
~monofilament possibly

12

Discrimination touch can be easily tested by

~2 pt discrimination
~2 sharp pts
~more in hands and face, less in back and thighs

13

Cortical sensory

~Traced figure (graphesthesia)- ~Stereognosis
~Double simultaneous

14

How to test for Graoheselsia?

draw an upper case figure somewhere on the back, etc

15

How to test for Sterognosis?

know if you are holding something, how much you are holding

16

How to test for Double simultaneous?

~different sides of the body at the same time (can be light touch, sharp, etc)
~Test bilateral, eyes closed, test randomly

17

Kinesthetic- meaning and how to test

~feeling the change of the length of tissue
~move the joint (lengthen or shorten the muscles) and pt should be able to tell us which direction we are moving them in
~Hold on sides of limb, so the pt cannot tell which direction you are moving it based just on pressure on limb.
~Could ask where in space the limb is
~Don’t have to have limb moving at that point

18

What is Proprioception?

feeling joint angle or position

19

Different types of sensations (or lack of)

~Anesthesia
~Hypoalgesia
~Hyperalgesia
~dysesthesia
~allodynia
~thigmesthesia
~thigmanestheia
~trichoesthesia
~pallesthesia
~pallanesthesia
~stereognosis
~asterognosis

20

Anesthesia

Loss of sense

21

Hypoalgesia

painful stimuli but mutes sensation (when you break your arm, you have a lessen pain then you should)

22

Hyperalgesia

heightened sensation to a painful stimuli (when you break your arm, you have an increase pain then you should)

23

dysesthesia

unpleasant or painful cutaneous sensory stimulus; pins and needles, etc

24

allodynia

~pain from non-noxious stimuli
~you sense pain from a non-noxious stimuli (when a person rests their hand on your shoulder, it is painful)

25

thigmesthesia

ability to feel light touch

26

thigmanestheia

inability to feel light touch

27

trichoesthesia

ability to feel the deflection of hair

28

pallesthesia

ability to feel vibration

29

pallanesthesia

inability to feel vibration

30

stereognosis

ability to know what is in out pocket without seeing it/ just feeling; ability to identify something by touch alone
